摘要： A control device (10) for a press machine, by which one of the slide (4) and the die cushion (6) is suitably controlled, when a malfunction occurs in the other, such that the force between the slide (4) and the die cushion (6) does not excessively increase. The control device includes a slide control part (12) for controlling the motion of the slide (4) and a die cushion control part (14) for controlling the motion of the die cushion (6). A first transmitter (18) transmits an abnormal signal from the die cushion control part (14) to the slide control part (12) when a first detector (16) detects a malfunction of the die cushion (6). The slide control part (12) is configured to move the slide (4), when receiving the abnormal signal, such that the slide (4) is away from the position of the die cushion (6) at the time of receiving the abnormal signal by a certain distance and, to stop the slide (4).

摘要： Disclosed is a controller for detecting need of maintenance, abnormal operation, etc. of a machine attributable to reduction of its strength caused by secular change. Acceleration detecting means are attached to driven elements that are driven by servomotors. Respective processors of axis control circuits for feedback-controlling the positions and velocities of the servomotors perform position and velocity feedback control processing for each position/velocity control period, thereby obtaining current commands, and output the commands to current loop processing. Detected acceleration values af are read from the acceleration detecting means. When the detected acceleration values a f are not smaller than a threshold value as, an abnormality signal is outputted, whereupon an alarm is displayed and the machine operation is stopped. Since the accelerations of the driven elements are detected directly by the acceleration detecting means, abnormality of the machine, such as frequent vibration attributable to aging of the machine, collision of the driven elements with other objects, or breakage of parts, can be detected securely.
摘要翻译：本发明公开了一种控制器，用于检测由于经年变化引起的强度降低而引起的机器的维护，异常操作等的需要。加速度检测装置安装在由伺服电机驱动的驱动元件上。用于反馈控制伺服电动机的位置和速度的轴控制电路的各个处理器对每个位置/速度控制周期执行位置和速度反馈控制处理，从而获得电流命令，并将命令输出到电流回路处理。从加速度检测装置读取检测到的加速度值af。当检测到的加速度值a f不小于阈值as时，输出异常信号，于是显示警报并停止机器操作。由于通过加速度检测单元直接检测被驱动元件的加速度，因此能够可靠地检测机械的异常，例如由于电机的老化引起的频繁振动，从动元件与其他物体的碰撞或者部件的损坏等。

摘要： An acceleration detection unit for detecting acceleration is mounted on a driven body. When a previous block is a positioning command, the system waits till the detected value of acceleration detected by the acceleration detection unit becomes equal to or less than a set value αs after the distribution of the movement command of the positioning command is ended. If the detected value of acceleration becomes equal to or less than the set value αs, the distribution of the movement command of the next block is started. Because the cutting feed, etc., is started after the detected value of acceleration has become equal to or less than the set value αs and the vibrations stopped, machining can be conducted with high accuracy.

摘要： Where high control precision is required in contour control or the like, mode B for a short PWM period is selected to assure a high control precision. Where high torque is required in fast feed, high acceleration or deceleration, mode A for long PWM period is selected so as to decrease the rate of the time of dead zone δ where voltage is not applied to the motor.

摘要： Current control for an AC servomotor for driving moving elements of a pressing machine is carried out by utilizing d-q conversion. A phase correction value θm is added to a rotor phase θr to compensate for a torque reduction associated with magnetic saturation. D-q conversion is effected in accordance with a three-phase actual current of a servomotor 4 and a corrected rotor phase θ (= θr + θm), whereby a d-phase current Id in the direction of a magnetic flux formed by a magnetic field system and a q-phase current Iq perpendicular to the d-phase current Id are obtained. Current loop control is effected with a q-phase current command used as a torque command and with a d-phase current command adjusted to 0, whereupon command voltages Vd and Vq are obtained. Conversion into three-phase voltage commands Vu, Vv and Vw is effected by means of a two-phase-to-three-phase converter 2, and the servomotor 4 is driven by means of a power amplifier 3. With this arrangement, there is no current loop phase lag, reactive current can be reduced, and high torque can be generated. Thus, high-speed operation can be carried out with reduced heat release from a motor.

摘要： In a controller, V axis and W axis for driving a driven body (3) are tilting, not orthogonal to each other. An acceleration detector (7) capable of detecting accelerations in a plurality of directions orthogonal to the driven body (3) is arranged so that W-axis direction may meet Y-axis direction of an acceleration detected by the acceleration detector. An acceleration (Av) in the V-axis direction is determined by making calculations from accelerations (Ax,Ay) in X-axis and Y-axis directions detected by acceleration detectors (7). Based on the determined accelerations (Av,Aw) in the V-axis and W-axis directions, a position command, a speed command or a current command to servo motors (2v,2w) driving the V axis and W axis is corrected. Such correction suppresses the driven body (3) from generation of vibrations.
